The fourth lamination on the tank base was laid down yesterday and when I came back to it this morning despite extensive use of the roller during lay- up it is evident that in a number of places the last lamination has separated and cured hard with an air gap to the previous lamination. I have decided to grind these areas back to take out the separated layer/area and patch them, not pretty but they will be on the inside of the tank.
On the flat area above where the carburettors will be there is still noticeable “flex” when pressure is applied to the centre of the flat area so another one or two complete laminations are in order. The structure is incredibly light (too big for the scales but less than 500 g) and another two laminations will only add about 300g but a significant piece of mind. The 4 mounting areas and any areas where the tank rests on rubbers on the frame near the steering head will also get additional reinforcement.
